projecting three-bay central pavilion with arched windows flanked by single-bay flat-roofed wings. Only Spring Valley's emphasizes the Greek Revival precedents of the style with the pilasters and pediment. Another architect, Jackson Flournoy, used them on his post office in the Queens neighborhood of Jackson Heights, also listed on the Register. Etnier's mural, meant to show how mail could and did reach even the most isolated people and linked the world, was added in 1938. Later renovations enlarged the lobby teller windows and added modern lighting. There have been no other significant changes to the building.
